In order to study adaptation and estimate Genotyp Envieronment Intraction and effect. Different Agropyron. .species to envieronment conditions. 10 popluation evaluated in three experiments with three repilaction sepatutly. The genotypes were planted in RCB decing and in four regions (Feraidounshar , Broujen , chadegan n.d, sernirom). The results of variance analgsis for forage yield, stemneisht. and Number of graminate , each of exprimnts showed significant different. The results of combine, analysis showed that three is significant differences.for genotypes , environment and GxE intraction effect. Stability analysis methods of Shukla, wricke and Eberhart-Russell were used for determination of the best genotype for yield, stem height and seed germinution. Based -on Eberhart-Russell. method in 1379-1380 experiment, Agropyron libaniticum had .the best general adaptation, and Agropyron gentryi had the best showed that genetry special adaptation. Wricke and shukla stability analgsis ecotype 'Agropyron gentryi' was better that others ecotypes. The correlation between protein percentage and forage dry matter yield was negetivesignificant, The correlation cofficient between dry matter yeild and stem heigth tiller number, spicke length, leaf length were positive significant. The association of ADF and digestibility was negative significant. Key words: genotype* environment, stability and adaptation, evaluation and yield
